ICD-10 Code H40.133 – Pigmentary glaucoma, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H40.133 – Pigmentary glaucoma, bilateral
What it is
H40.133 identifies pigmentary glaucoma affecting both eyes. It is a form of glaucoma associated with pigment dispersion and optic nerve damage.
Clinical signs
Typical findings include pigment in the anterior chamber, trabecular meshwork, and signs of glaucomatous optic neuropathy. Clinical features vary; refer to documentation.
When to use this code
Use H40.133 when the provider documents pigmentary glaucoma in both eyes. It also fits follow-up visits when bilateral disease is confirmed and the diagnosis remains active.
Do not rely on symptoms alone; the record should support glaucoma and laterality. If the note only mentions pigment dispersion without glaucoma, check documentation.
Do not use for
Do not use this code for unilateral pigmentary glaucoma or for pigment dispersion syndrome without glaucoma. Check documentation if laterality is unclear.
Coding tip
Verify both the glaucoma type and bilateral involvement before assigning H40.133.
